talk to kennedy power. he's doin a deal on porting right now and shearer's new pipe for like $400 i believe, someone correct me if i'm wrong.
but as for reeds not making it faster, they may only make it snappier on a stock blaster, but the stock reeds can only flow so many cfm so once you get your motor wanting to breathe more than that (ie with a port job and pipe) aftermarket reeds are going to make a diffference.
